TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 575,147, dated January12, 1897.

Application filed January 7, 1896. Serial No. 574,639. (No model.)`

To ctZZ whom it may concern:

Be it known that we, LEE S. BURRIDGE and NEWMAN R. MARSHMAN, residentsof the city, county, and State of New York. have invented certain newand useful Improvements in Type-W'riting Machines, of which thefollowing is a specitication.

Our invention relates to type-writing machines, and has 'reference moreespecially to improvements upon the type-writing machine for which wefiled an application for Letters Patent, Serial No. 567,608, November l,1895.

The object of our invention is to provide a simple and etlicienttype-writing machine wherein a sheet may be employed as an inker and maybe automatically and continuously fed by the operation of the machineproper so as to present a different surface to a printing-characterafter an operation of each of such printing-characters. V

Ourinvention consists in the special matters hereinafter set forth andclaimed, and will be explained with reference to the accompanyingdrawings, in which- Figure 1 is a plan view of a type-writer embodyingone form of our improvements. Fig. 2 is an enlarged sectional viewthereof, the section being taken on line 2 2 of Fig. l. Fig. 3 is aperspective view of the machine with the carriage raised and theinker-carrier swung on its pivot in order to more clearly show the saidinker and inker-carrier. In this view some of th-e parts are omitted inorder that the inker and inker-carrier may be shown clearly.

Referring particularly to the drawings, wherein portions of atype-writing machine of the Remington type are illustrated, A is themain body or frame of the type-writer, uponwhich are carried the usualback rod a and shifting rod a', upon which the carriage B travels, thecarriage being hinged upon the back rod in the usual manner. Thecarriage B also carries the usual impression-roller or paper-platen Cand paper-roller D.

The impression-roller is rotated in any usual manner by means of a pawlc, which is carried upon the usual operating-lever E, which is pivotallyhung at c and extends downward to form the usual handle F.

Projecting from the carriage B are the usual recessed lugs b2, whichpersons skilled in the art will recollect have heretofore been the studsl), projecting from the lugs b', and i serve to supporta supportingbracket or table G, which in the present instance is shown as withflanges g at the ends.

Seated in slots` in the flanges g and retained .by the brackets h is arock-shaft j, which carries arms 7o, upon one of which a toothed segmentZ is carried, a spring 253 tending to pull said arms and segment in adownward direction.

Carried by each of the arms 7c is an inkerengaging device, shown in thepresent instance as consisting of a claw m.

The toothed segment or segmental rack Z is located adjacent to a bracketH, which rises from the carriage B, and is provided with a shaft n, uponwhich a ratchet-wheel 0 and a mutilated pinion p, connected therewith,are mounted. The mutilated pinion 1J engages with the segmental rack Z,a click q, which is spring-impelled, serving to prevent a reverse motionof the ratchet and pinion.

An arm I is pivoted to the bracket by one end and carries a pawl r,which is springpressed and engages in the teeth of the ratchet 0. A rodJ depends from the arm I and has a toe s, which extends beneath thelever E.

Brackets K depend from the socket b'. In these brackets is pivoted aframe or inkercarrier comprising bentwire sections t u, which enter theeyes of the rods K, and the wire section fv, which forms the front ofthe inker-carrier, the rods utbeing joined thereto by means of ears c w.The horizontal portions of these ears bear upon the shifting rod andproject over the same to a considerable extent, so as to allow thenecessary backward movement of the shifting bar when it is shifted toallow of upper-case characters being printed, the ears at the same timeallowing the passage and free movement of theguides L of theroller-shifter which embraces the shifting rod when the carriage andinkercarrier are IOO down, as shown in Fig. 2, which represents theparts shifted to print upper-case characters. Each wire tu is surroundedby a spiral spring t" a', each of which terminates in a hook or engagingdevice t2 u2.

A plate M is carried upon the frame of the inker-carrier and is providedwith ears y, between which a rod .e extends.

O is the inker, which is shown as of sheet form, and is engaged at itsforward end by the hooks 2 u2 and at its rear end by the claws m, thesaid inker passing under and behind the rod or guide .2' and being kepttaut by the springs t' u.

Vhen the carriage is down, as shown in Fig. 2, the machine is inposition to print or write, any usual printing agent, as N, beingemployed.

It will be observed that although we have shown the inker-carrier asattached to and moving with the carriage in its travel from end to endof the machine, yet nevertheless the Ycarriage may be raised withoutraising theinker-carrier with it. The inker-carrier is, however,` shownin the present instance as capable of being swung on its own pivotindependently of the carriage. By this means the inker-carrier can, whendesired, be swung on its pivot from over the type-well to give access tothe types for cleaning and other purposes.

The operation of our device is as follows: Supposing the parts to be inthe position shown in Fig. 2, the type-writer is manipulated to write inthe usual manner, the printing agent striking the inker and pressing itagainst the paper which is carried on the impression-roller or platen C.When the end of the line has been reached, the handle-operating lever Fis manipulated in the usual manner to release the rear rack (not shown)from its cooperating part and to permit the carriage kto be slid backalong its guides to start anew line. By the same operation theimpressioirroller is stepped around to shift the paper to `the nextline, and the lever E, coming against the toe s of the rod J, draws downupon the said rod, thereby swinging the leverl on its pivot and movingthe joined wheels o p around one step by means of the pawl The movementof the pinion p has the effect of swinging the toothed segment l, withwhich it meshes, thereby pulling on the inker O against the tension ofAits springs t2 u2 and drawing it back a short distance to present a newportion of the inker to the printing characters after each line iswritten. This operation vis repeated each time the impressionroller Cisshifted to start a new line, and thus as the machine continues to beoperated the inker is drawn back gradually as the arms k are ,swungontheir pivot. Presently, however', the pinionfp willhave been rotatedfar enough to lbring the mutilated part p thereof opposite l thesegmental rack and to disengage the teeth of the pinion from those ofthe segmental rack. Thereupon the segmental rack, being no longerengaged with the pinion, will, through the medium of the springs t', u',and t3, be swung downward, the springs t' u also serving to throw theinker into its extreme forward position, which is shown in Figs. l and3. Further revolution of the wheel 0 will rengage the mutilated pinion pwith the segmental rack, and the operations will be repeated.

It will thus be observed that by our invention the inker isautomatically fed longitudinally or in the direction of the feed of thecarriage and is also automatically fed at right angles to the feed ofthe carriage, so as to automatically and continuously present adifferent portion of the inker after each impression of aprinting-character.

While our invention has been illustrated as combined with certainportions of a typewriting machine of the Remington Y type and as beingapplicable to such a machine without in any way changing theconstruction of such machines as at present existing, we would have itdistinctly understood that we do not limit ourselves to the use of ourimprovements to a type-writing machine of any particular type.

It will be obvious to those skilled in the art that the apparatus whichWe have shown for carrying out our invention is susceptible of manyVariations, dependent upon the circumstances of use.

What we claim, and desire to secure by Letters Patent, isy l. Thecombination with a mechanical writing-machine, of an inking devicecomprising van inker and means for automatically'moving the printingportion of the inker in ,one direction in `one plane by the travel of,thefearriage, and means for moving the printing portion of the inker Aatright angles thereto in the same plane as `before by a rotation of theimpression-cylinder, and restoring means for automatically bringing theinker to the initial position. 4
